What you are comes from the blood of those who set you on this journey. That is likewise unchangeable. What you see in the reflecting pool of truth is who you are. You cannot change that, so it is wise not to curse it. The wiser choice is to embrace it and make it your strength.
We are all afraid of something. But that shouldn't stop us from going on every day. We should not always walk in fear of the shadow while we are in the light. It is certain we will not know when or how the difficult and bad times will come, but if we accept that they will come, then they are easier to face when they do. And always remember that anything that causes the shadow is smaller than the source of light.
Weakness and strength are necessary for balance. No one or nothing is only weak or only strong. But some of us overlook our weaknesses, and even deny that we have them. That can be dangerous, because denying there is a weakness is in itself a weakness. Likewise, accepting that we have weaknesses becomes a strength. And by the same token, overestimating strength is a weakness. You should not be blinded by your strengths. The feeling of strength is not the same as having strength. Neither should you ignore your weaknesses. Know them well, too.
